just curious, do you have guys have the contrasts materials during the CT scan? I read from the net saying it can provide some mild discomfort and worst case, could have the metallic taste. is that true?

2ndly, i am not sure how safe is this CT Scan as it uses x-rays which are 1 of the cause of cancer. This is my 1st time and my company is having the benefit do to a medical checkup every year. So, thought of giving it a try.
